Abstract
Se proporcionan sistemas y métodos para controlar la producción de clorato en celdas de electrólisis. Los métodos pueden producir una disolución que contiene hipoclorito que tiene una relación de clorato a cloro libre disponible de menos de 0,1 al poner en contacto un flujo de una salmuera que contiene cloruro con una corriente de alimentación acuosa para obtener una mezcla. La tecnología descrita también incluye modular al menos uno del caudal de la salmuera que contiene cloruro y la concentración de cloruro de la salmuera que contiene cloruro para producir la disolución de producto que contiene hipoclorito.Systems and methods are provided to control chlorate production in electrolysis cells. The methods can produce a hypochlorite-containing solution having a chlorate to available free chlorine ratio of less than 0.1 by contacting a flow of a chloride-containing brine with an aqueous feed stream to obtain a mixture. The disclosed technology also includes modulating at least one of the flow rate of the chloride-containing brine and the chloride concentration of the chloride-containing brine to produce the hypochlorite-containing product solution.
